Abstract

The invention relates to a method for electrodepositing metal copper on surface of textile by using constant current. The method comprises the steps of soaking the textile in an inorganic acid solution of a nitrogenous macromolecular monomer, oscillating, and then sprinkling an ammonium persulfate oxidizing liquid on the textile to obtain conductive textile, performing constant-current electrodeposition on the conductive textile in an electrolyte, rinsing and drying. The preparation method is simple, simple in solution composition, safe and friendly to the environment, and low in cost; conductive metal layers different in micromorphology can be obtained by controlling the current density; and the method has a wide application prospect in the intelligent textile field.

Description

technical field [0001] The invention belongs to the field of preparation of conductive fabrics, in particular to a method for constant current electrodeposition of metal copper on the surface of textiles. Background technique [0002] The direct metal electrodeposition (direct electroplating) process on non-metallic surfaces began with the discussion of the direct metal electrodeposition process on plastics. The traditional method of depositing metal films on the surface of non-conductive substrates is often achieved by electroless deposition (electroless plating), but the process involves Expensive noble metal salt catalysis, the use of formaldehyde as a reducing agent and the generation of hydrogen in the electroless deposition process are prone to pinhole pitting of the coating, which affects the apparent quality of the coating. In view of the existence of the above problems, people began to explore the direct electrodeposition process of non-conductive substrates while c...
